Skiving is a relatively new metal working technique, and it is very similar to the act of hand planning a block of wood except that 'shavings' are shorter and remain attached. The benefit of a skived heatsink has always been the lack of a thermal joint between the fins and base, since each is formed from the same raw material. FrostyTech has tested out one of the latest socket 754/939/940 AMD Athlon64 heatsinks called the Dynatron A22. The heatsink at first appears to be nothing more than a plain aluminum skived heatsink, but closer examination reveals a couple very effective innovations, not the least of which are the V-shaped fins.
